Abstract
A data storage device includes a substrate and one or more grid array integrated circuit packages. The grid array integrated circuit package includes at least one self-alignment pin having a tapered shape. The substrate includes one or more connection pads to receive the grid array integrated circuit packages. The connection pads include at least one self-alignment receptacle that receives the self-alignment pins such that the grid array integrated circuit packages maintain an alignment with an associated connection pad of the substrate.
Claims16
A data storage device, comprising:
- a substrate;
- and
- an integrated circuit package including:
- a grid array, and
- at least one self-correcting alignment pin having a tapered portion;
- and
- wherein the substrate includes a connection pad interfacing with the integrated circuit package, the connection pad including at least one self-correcting alignment receptacle receiving the at least one self-correcting alignment pin,
- wherein the self-correcting alignment receptacle has a tapered shape complementary to a shape of the tapered portion of the at least one self-correcting alignment pin, and
- wherein the self-correcting alignment receptacle does not penetrate completely through the substrate.
An integrated circuit device, comprising:
- a package having a quadrilateral shape;
- a grid array positioned on a first side of the package, the grid array including a plurality of connection points;
- a first self-correcting alignment pin on the first side of the package;
- and
- a second self-correcting alignment pin on the first side of the package,
- wherein the first self-correcting alignment pin and the second self-correcting alignment pin each have a conically shaped tapered portion;
- and
- wherein the first self-correcting alignment pin and the second self-correcting alignment pin are positioned opposite the grid array along a diagonal axis bisecting the package, and
- wherein the integrated circuit device is coupled to a substrate, the substrate comprising a connection pad configured to interface with the integrated circuit device;
- and
- wherein the first self-correcting alignment pin and the second self-correcting alignment pin interface with a first self-correcting alignment receptacle and a second self-correcting alignment receptacle, respectively, of the connection pad,
- wherein the first self-correcting alignment receptacle and the second self-correcting alignment receptacle have a tapered shape complementary to the conically shaped tapered portion of the first self-correcting alignment pin and the second self-correcting alignment pin, and
- wherein the first self-correcting alignment and the second self-correcting alignment receptacles do not penetrate completely through the substrate.
An electronic assembly, comprising:
- a printed circuit board including a connection pad;
- and
- an integrated circuit package having a grid array;
- wherein the integrated circuit package includes a first self-correcting alignment pin and a second self-correcting alignment pin that have a tapered portion, and
- wherein the connection pad is interfaced with the grid array, the connection pad including a first self-correcting alignment receptacle receiving the first self-correcting alignment pin and a second self-correcting alignment receptacle receiving the second self-correcting alignment pin, and
- wherein the first self-correcting alignment pin is received within the first self-correcting alignment receptacle and the second self-correcting alignment pin is received within the second self-correcting alignment receptacle such that the grid array integrated circuit package maintains an alignment with the connection pad,
- wherein the first self-correcting alignment receptacle includes a tapered shape complementary with the tapered portion of the first self-correcting alignment pin and the second self-correcting alignment receptacle includes a tapered shape complementary with the tapered portion of the second self-correcting alignment pin;
- and wherein the first self-correcting alignment receptacle and the second self-correcting alignment receptacle do not penetrate completely through a substrate of the printed circuit board.
